300 Posted September 27, 2017 Report Share Posted September 27, 2017 Hello. Went to a new lake the other day. Horseshoe by Parry Sound My Elite5 had Sonar but no navigation. It's like it didn't recognize the lake. Any tips ? Thanks Link to comment Share on other sites More sharing options...
Fisherman Posted September 27, 2017 Report Share Posted September 27, 2017 Is the chip in the slot? Link to comment Share on other sites More sharing options...
Rizzo Posted September 28, 2017 Report Share Posted September 28, 2017 not all lakes have been mapped would be my guess...and even if it had, is that lake included in your Package on the chip you have Link to comment Share on other sites More sharing options...

craigdritchie Posted September 28, 2017 Report Share Posted September 28, 2017 Lowrance has an online service called Genesis that lets you create your own charts. Record your data on an SD card then upload it to the website. You can share the data, or mark it private. Then put the card back in your graph and download your new map. There are lots of YouTube videos that walk you through the process. The maps are only as good as the data you feed into it. Make two or three passes through a bay and its pretty sketchy. After multiple passes over multiple trips it gets to be surprisingly detailed. Link to comment Share on other sites More sharing options...

AKRISONER Posted September 28, 2017 Report Share Posted September 28, 2017 Much of georgian bay is also not charted...take a look at the area around the shawanaga river you will see that there is nothing there. Link to comment Share on other sites More sharing options...
spincast Posted September 28, 2017 Report Share Posted September 28, 2017 Have you done any updates ? Likely, the lake isnt charted on the device / chip. To find out put chart on full screen (you can do this from home) zoom out. waaaay out so that you are like google earth view, all of ontario. now slowly zoom in. you should see dotted lines on the chart. These are the charted / uncharted zones. If your lake is outside the dotted line where you have depths, you need a different card. You can check by identifying an area you know is charted, and look to a lake just outside the dotted line that one is in. Zoom in looking for contours on each lake. If you ever get out Woodstock way, you can take it into Angling outfitters. They'll answer all your questions, as well as know the card that has your lake on it........ Just don't be in a hurry Link to comment Share on other sites More sharing options...
